Best way to test a high current pcb design 70A @ 12V


I designed a circuit (MOSFET HBRIDGE) that Should Be able to handle 70A @ 14V. Now that the board is sent out I am on to thinking about how to properly test it.


Right now the most logical way I have to test it is to take a bunch of power resistors and hook it up to a SLA 12V Battery.


I would start w/ 15A then maybe 35A then 50A or something to that extent. I would monitor the temperature on both the fets and the traces themselves.


Any other suggestions would be appreciated.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
